What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid - DEF is 32.5% solution of high-purity urea in de-mineralized water that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of nitrogen oxides (NOx) from the exhaust systems of diesel vehicles. Diesel Exhaust Fluid - DEF is clear non-hazardous liquid. It is not a fuel, nor a fuel additive and needs to be filled into a dedicated Diesel Exhaust Fluid - DEF tank which is on your diesel vehicle. It is replenished in a similar way to refueling diesel. Should you spill Diesel Exhaust Fluid - DEF on your hands, simply wash it off with water.
How much do I need?
Average consumption of Diesel Exhaust Fluid is generally 2% per gallon of diesel fuel, so you will need to tank much less for DEF then you do for diesel fuel. 2.5 gallons of Air1 Diesel Exhaust Fluid will yield over 350 miles of travel.
How much does Diesel Exhaust Fluid cost?
Diesel Exhaust Fluid cost depends on the volume of your usage, and the Diesel Exhaust Fluid package that you order. Contact Tim Fields for a Diesel Exhaust Fluid price.
Diesel Exhaust Fluid storage.
Diesel Exhaust Fluid needs to be protected from extreme temperatures. Diesel Exhaust Fluid's freezing point is at 12 degrees Fahrenheit (-11 Celsius). When DEF thaws, the product will retain its initial quality and vehicles will remain operational throughout the Diesel Exhaust Fluid tank thawing process. DEF should be stored in a sealed package and in a well ventilated storage area.
